Product Summary:

Fire-Lite B224BI Addressable Loop Isolator Base

A mounting base that augments a Fire-Lite detector with an isolator, which allows loops to continue to operate under fault conditions and automatically restores them when the fault is removed

---

The Fire-Lite B224BI is a mounting base that augments a Fire-Lite detector with an isolator, which allows loops to continue to operate under fault conditions and automatically restores them when the fault is removed.

• Diameter: – B501: 4.1" (104 mm).– B224BI, B224RB, B350LP: 6.1" (155 mm). – B501BH-2, B501BHT-2: 6.0" (152 mm). – B200SR: 6.875" (17.46 cm).
• Wire gauge: – B224BI, B224RB: 14 to 24 AWG. – B350LP, B501, B501BH-2, B501BHT-2, B200SR: 12 to 24 AWG.
• Temperature range: – B224BI, B224RB, B501BH-2, B501BHT-2, B200SR: 32°F to 120°F (0°C to 49°C). – B501 and B350LP, -4°F to 150°F (0°C to 66°C).
• Humidity range: 10% to 93% RH, non-condensing.
• System temperature and humidity ranges: This system meets NFPA requirements for operation at 0°C to 49°C (32°F to 120°F); and at a relative humidity (noncondensing) of 85% at 30°C (86°F) per NFPA, and 93% ± 2% at 32°C ± 2°C (89.6°F ± 1.1°F) per ULC. However, the useful life of the system’s standby batteries and the electronic components may be adversely affected by extreme temperature ranges and humidity. Therefore, it is recommended that this system and all peripherals be installed in an environment with a nominal room temperature of 15°C to 27°C (60°F to 80°F).
